What is the reason for the brittleness of injection molded products?
Aspects of the selected molding equipment
If there are obstacles in the barrel of the injection molding machine, it is easy to cause the melt to degrade;mould supplier ,if the plasticizing capacity of the machine is too large, the heating and shearing time of the plastic in the barrel is too long, the plastic is easy to age, and the product becomes brittle.
mold
The gate of the injection mold is very small. At this time, it is necessary to consider adjusting the gate size or adding an auxiliary gate. If the shunt channel is too small, try to balance the arrangement or increase the size of the shunt channel. Poor mold structure leads to abnormal injection cycle.
plastic product design
Products with sharp corners, notches, or parts with large thickness variations are prone to stress cracking. The product design is too thin or too hollow.
